Petrochemical / high-pressure gas pipeline
Pilot-Operated Safety Valves
Gas
High-pressure gas-pipeline service requiring precise set-pressure control, stable discharge performance and reliable seat tightness.
Precise set-pressure behavior, stable discharge, small blowdown and strong seat-tightness performance for gas service.
Batch supply of pilot-operated safety valves selected for the project service requirements.
- Tight set-pressure tolerance and repeatability were key selection requirements.
- Pilot-operated architecture selected for the high-pressure gas duty.
- Small blowdown and seat tightness were important operating criteria.
Inspection, testing and documentation followed the applicable project/order requirements. Detailed records are available through project-specific technical review.

Full-Nozzle Safety Valves with Balanced Bellows
Steam
Steam-pipeline service with outlet backpressure, requiring full-nozzle discharge capacity and balanced-bellows stability.
High discharge capacity with a configuration that reduces the influence of outlet backpressure on stable relief performance.
Full-nozzle safety valves using balanced-bellows configuration for the project steam system.
- Full-nozzle construction selected for higher discharge-capacity demand.
- Balanced bellows reduce the influence of outlet backpressure on valve operation.
- Configuration selected for steam / thermal-system relief duty.
Applicable project inspection, testing and technical documentation were controlled with the supply; exact records are not generalized beyond this project.

One controlled path from RFQ to shipment.
The exact deliverables depend on the purchase order, project specification and inspection plan. The workflow below is the normal control sequence.
RFQ
Collect service conditions, product requirements, standards, quantities and document scope.
Sizing
Confirm calculation basis, required area/capacity and configuration assumptions.
Technical Approval
Submit datasheet, calculation, drawings, certificate matrix and deviations for review.
Manufacturing
Procure and manufacture against the approved configuration and controlled BOM.
Inspection & Testing
Complete required material, process and performance inspections with witnessing where specified.
MDR
Compile approved drawings, material certificates, test records and conformity documents.
Shipment
Release after required approvals, document completion and shipping preparation.
Project delivery depends on more than the valve body.
Safety Valves
Review the six product families and their actual model-level performance scope.
Engineering & Sizing
Turn service data into a calculable valve selection and technical quotation.
Quality & Testing
Review traceability, inspection, set-pressure and performance-test capability.
Start with the service data and required documents.
Send the specification, datasheet or existing valve nameplate together with the operating conditions. HHSV can prepare the sizing basis and technical quotation.
